GLASS-BLOWING MACHINE.

SPECIFICATION forming' part of Letters Patent No. 669,524, dated March12, 1901.

Application filed March 21| 1900. Serial No. 9,623. (No model.)

To all whom it may concern:

Be it known that I, HEINRICH WILHELM HEERDT, a citizen of the Empire ofAustria- Hungary, and a resident of Aussig, (whose post-office addressis Prodlitzerstrasse No. 91 1, Aussig,) Austria- Hungary, have inventedcertain new and useful Improvements in Glass-Blowing Machines, of whichthe following is a specification.

The present invention relates to an improved glass-blowing machine,principally for the manufacture of bottles, which is adapted to beoperated by two persons and will produce, according to size and nature,from one hundred and fty to two hundred bottles per hour.

In the annexed drawings the machine is represented as a whole and indetail.

Figure 1 is a front view of the machine; Fig. 2, a side view with theparts to the left of the line A B in Fig. 1 omitted. Fig. 3 is a view ofthe work-table in plan, and Figs. 4 and 5 show the device for operatingthe pistonof the blowing apparatus from the side and in plan. Fig. 6shows the device for turning the forming-tool, and Figs. 7 and 8 thedevice for cutting off the glass, while Figs. 9 and 10 show thepress-mold in vertical section and from below.

The construction of the machine is as follows:

The work table l rests upon a movable frame, and from its surface, closeto the two narrow edges, rise two supports 2 of a bridge 3, which can beraised or lowered by means of the screw-nuts 4. Into this bridge threecylinders are inserted vertically. In the center one of these, 5, thepiston of the rammer 6 moves, while each of the pistons of the two sideones, 7, is provided with a llong formingtool 8 in a socket 9. At eachsidcof the three cylinders is a blowing-stamp 10, also passing throughthe bridge. Upon the Work-table are four molds, two of which, in themiddle, are press-molds 11, of uniform construction, and twoblowing-molds 12, also of uniform construction, one at each end. Duringthe manufacturing process one of the press-molds 1l is inserted upsidedown into the neck 13 in the middle of the table, (see Figs. 9 and 10,)which fits around the neck of the mold, while the other press-moldremains upright on one of the plates 14E, the upper part of whichreachesinto the mold and is forced apart from the lower part by means ofa spring. The rammer 6 above the inverted press-mold has a head 15,which is removable and correspondsin diameter to the inside of thepress-mold which is being used. The rammerand its piston are operated bypressingdown the handle l6,and thereby opening the valve 17 of thecompressed-air pipe 18, whereupon compressed air enters the cylinder 5above the piston. When the valve has been closed again after the pistonhas been forced down, the latter is forced up again by a spring in thecylinder. Both the valve 17 and the two valves 17 of the forming-toolcylinders are duplex valves, which when closed connect the interior ofthe cylinder with the outer air and when open connect the interior ofthe cylinder with the compressed-air supply. The upward-and-downwardmovement of the pistons 9 with the movable tools 8 is effected in thesame manner. In the case of these, however, the forming-tool is causedto revolve around its own longitudinal axis during the movement in orderthat it can be easily withdrawn from the glass lump and that the mouthof the bottle will be smooth. For this purpose, as shown in Fig. G, thepiston has a projection 19, which runs in the helical groove 2O in theguides. On pressure being brought to bear on the piston in the cylinder7, the piston and socket 9, and therefore the tools 8, are forced duringthe descent to follow the winding of the helical groove, andconsequently to revolve around theirlongitudinalaxes. The sametakesplace during the ascent, which is caused by the spring 21.

In the case of the two blowing-stamps 10 the compressed air, which isintroduced from above and passes through the hollow stamp, only servesto blow the lump in the blowingmold l2. The downward movement of thisstamp is caused by means of the hand-lever 23, Figs. 4 and 5, with thecounterweight 22. A rectangular projection 24 of the said lever graspsthe stamp and presses upon a horizontal plate 25, which slides upon thestamp. This plateis connected, by means of two rods 26, with a plate 27,sliding upon the stamp higher up and guided by two rods 28, which alsoserve as guides for the stamp itself. The

ICO

plate 27 is supported by a helical spring,

which rests upon-a'third plate 30,tixed to the Y stamp and through whichthe con necting-rods 26 pass. When the lever 23 is drawn downward intothe horizontal position, the spring,

pressing against 4the fixed plate 30 and not yet compressed bythe plate27, causes the stamp to descend until it rests upon the mold.

On the lever being forced down still farther) the spring is compressedas the stamp is resting upon the mold and the two plates 25 and 27,connected together, are lmoveddown-ward.,

pressed-air apparatus by means of a pipe 36.

The press-mold 11 is a thick-sided hollow mold, Fig. 9, with theenlargement 37 for the mouth-lip. the blowing-mold and flared at thebottom.

The press-ring 38 fits into the hollow at vthe bottom, and its handle 39passes 'through au of glass. When it is full, the projecting glass iscut o and the press-ring 38 applied byz hand, as in ordinarypress-molds. The pressring serves also as a guide for the head 15 of therammer 6.

To facilitate the inverting and reserving after pressingl of thepress-mold, the following device is provided: The two halves of the moldare, as usual, connected by hinges 41, Figs. 2 and 3, the pins 42 ofwhich are jointed to the `horizontal axle 43 of a reel 44. Upon each ofthe handles 45 of t-he mold is a short semicylinder, -which together`form a complete cylinder. By means of the reel and the cylinder themold can be rolledto and fro on the two parallel rails 47, provided. atthe back and the front, and can easily be turned over. For this purposeit must,'however, first be lifted from the neck 13 or the plate 14,respectively. In order to facilitate this,"which requires some exertion,as the bottoms t down tightly, the rails carrying the reel 44 and thecylinder 46, and consequently the whole mold, are fixed to the supports48, which slide vertically in the work-table and can be elevated bymeans of a lever device operated by compressed air, while when the leverdevice is put out of operation the weight of the mold forces the railsdown again. 'The said lever device (see Fig. 2) `consists of thedouble-armed levers 49, upon the outer arms of which 'the rails rest.The said outer arms are provided with weights 50. Theinner arms of thesaid levers arefjoi'nted to the T-shaped head (see Fig. 1) of apiston-rod 51, which moves `in a cylinder ports 48, carrying the rails.

Compressed air is 'lhe handlever 23 can be fixed in the horizontal oroperative position by means of the spring-click; 35, which catches inthe segment 34. The blowing-stamp is connected with the comnot placedcrosswise, but side by side. It is considerably narrower than 52, placedupon the lower frame ofthe machine. On the valve 53 being openedcompressed air from the pipe 16 enters above the piston 5l, which drawsone arm of the levers downward, and consequently lifts the sup- Each -ofthe two rails is divided in the middle, so that one half can be elevatedwithout the other. Of course an elevatingdevice is provided for eachpair of rails. (See Fig. 1.) A continuous current of air flows th roughthe nozzles 54 against the press-molds in order to keep the latter cool.

With the machine herein described the glass brought on the pontil is cutoff mechanically in order to save the operator the trouble ot' pickingup and Ylaying down the scissors. As shown in Fig. 2, a cutting device,which is represented on'a Alarger scale in Figs. 7 and 8, is providedi-n the middle of the tavble behind the inverted press-mold. The rodrv56 slides vertically in thesupport 55, the end pointing toward thepress-mold being turned upward and carrying the pivot 57 of the scissors58, the levers and blades of which are In order to move the openscissors above the `mold l1 and to close them there, vthe double- -armedlever 59 is jointed to the rod 56, carrying the scissors. The short arm60 of the lever'is connected with the piston 6l of 'the cylinder 62,provided beneath the table,

while the long arm-extends beyond its articulation to the 4rod 56 andthen bends downward and broadens into the shape of a rhombus. Oncompressed air acting nponthe piston of the cylinder 62 the upper -partof the lever 59 forces lthe Arod 56, carrying the open scissors, forwardtoward the mold 11. When therefore, in the following manner: Theoperator, who stands behind the table near the furnace, takes some glassfrom the pot with the pontil 65, Fig. 2, and holds it above the invertedmold 11, standing in the center of the table, resting the pontil uponthehook 66, Xed to the compressed-airpipe 18, the valve 67 of whichoperates the mechanical scissors. When sufficient glass lhas run intothe mold, the operator opens thevalve 67, which causes the mechanicalscissors to cut ott' the glass. Thesame oranother operator standinginfront of the; machine places the press-ring 38 upon the press-*mold 1land draws down the lever 16 of the valve 17, and thus causes 'the rammer6 to descend, which compresses the glass in the mold, in doing whichythemouth-lipis completed externally. Then he opens the IOO IOS

ITS

valve 53, operating the lever device of the rails 47, and rolls themold, turning it upright at the same time, to the right or the left toabove one of the plates 14 and closes the valve `53, so that the railsdescend with the mold and the latter is left standing upright upon theplate. Then he opens the valve I7 by pulling down the correspondinghandle. The' corresponding forming-tool descends while rotating, entersthe mouthpiece of the lump hanging in the mold, and ascends againimmediately the valve is closed. Then the operator opens the mold, takesthe lump out with a pair of tongs, and places it into the blowing-mold,which he then closes so far that the lump remains visible between thetwo parts ot the mold. He then pulls the lever 23 into the horizontalposition, and thereby causes the blowing-stamp l0 to descend to theblowing-mold 12, which he does -not close entirely until the lump hasexpanded sufciently. Then he opens the air-valve by pulling the lever 23down entirely, upon which compressed air enters and blows out the lumpinto a bottle.

All parts of the machine, except the rammer and the scissors, areprovided in duplicate, so that while the lump is being completed in theblowing-mold another one may be taken in hand.

Having now particularly described and ascertained the nature of thisinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1.
